In which condition can optical ambiguity of form occur?

Answer and explanation

Correct answer: A value pattern makes depth read in reverse or in two different ways.

Optical ambiguity occurs when visual cues allow more than one convincing interpretation of an object's form, depth, or orientation. Value patterns are especially important because light and dark areas can make a surface appear raised, recessed, tilted, or reversed. Option A provides exactly this condition: the same value arrangement causes depth to be read in two ways or in an opposite direction. Options B, C, and D describe stable and supportive cues that clarify volume rather than confuse it. Therefore A is the correct answer because it creates perceptual uncertainty in the reading of form.
